An new update to the metadata analytics stream will be introduced in AXIS OS 12.1, scheduled for release in November 2024. For detailed information about upcoming features, please visit the AXIS OS Portal.
Adding the operation “Rename” to the Analytics Scene Description metadata producer
The “Rename” feature is applied when an object receives an initial ID, temporarily loses it (e.g.,upon exiting the scene), then receives a new ID (e.g. upon re-entering the scene), and finally returns to its original ID thanks to the ReID technology.
This option allows the system to recognize what would otherwise appear as two separate tracks as one continuous track.
The main benefit of this operation is ensuring accurate tracking in more difficult conditions and in challenging situations by reliably reidentifying objects. Clients interested in gaining this benefit need to implement support for the "Rename" operation, otherwise objects that re-appear will continue to be handled as two separate tracks
Example:
The object begins with ID 1, exits the scene, returns with ID 2, and later reverts to ID 1.
When ID 2 changes back to ID 1, the rename function signals that these two tracks are connected to one continuous track.
